Reviews of the One Wish Too Many

I saw this film over 35 years ago, but it has stuck in my mind ever since. It tells the story of a boy who finds a magic marble which grants his wishes. He uses it to get revenge on some children who had been bullying him at school and to make raise his image amongst his schoolmates. As is often the case in stories involving items which grant wishes, his poor choice of wish eventually creates more trouble than help. It endeavors to show that taking revenge on bullies is not the necessary answer to their bullying and in itself may result in a worse outcome. It manages to do this in a very entertaining manner, which relates to the mindset of young children.
